So sorry to hear that :( Maybe next time if you want a nice rooster, try a gentle breed like a welsummer. They grow nice and big and mine Protected my flock from 3 vicious dogs. And he was nice and tame. But it’s up to you of course.
If he gets too aggressive, such as trying to really harm you, the best way to deal with him is, sadly, butcher him or give it to someone else to butcher.
